Key Parameters

Substitute Part Grouping Explanation

Substitution of the CBRLD1-04 TR13 is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage Rating: Peak reverse voltage must equal or exceed 400 V
• Current Rating: Average rectified current must equal or exceed 1 A
• Diode Configuration: Single-phase bridge rectifier topology
• Package Type: 4-SMD, Gull Wing surface mount configuration
• Temperature Range: Operating range must encompass -55°C to 150°C
• Forward Voltage Characteristics: Maximum forward voltage at rated current

The ABS4U from SMC Diode Solutions meets all substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The ABS4U is the direct equivalent substitute for the CBRLD1-04 TR13. Both components share identical electrical ratings, temperature specifications, and package configurations. The ABS4U offers the advantage of active product status with ongoing manufacturing support, whereas the CBRLD1-04 TR13 is obsolete.

The ABS4U demonstrates improved reverse leakage characteristics (5 µA versus 10 µA at 400 V), indicating superior device quality. Forward voltage is marginally higher at 1.1 V compared to 1 V, a difference of 0.1 V that remains within acceptable tolerance for standard bridge rectifier applications.

The ABS4U carries ROHS3 compliance certification, supporting modern environmental and regulatory requirements. Both components maintain identical moisture sensitivity ratings and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the ABS4U directly replace the CBRLD1-04 TR13 in existing designs?

A: Yes. Both components are single-phase bridge rectifiers with identical 400 V / 1 A ratings, operating temperature ranges, and 4-SMD Gull Wing package configurations. Pin-to-pin compatibility is maintained.

Q: What is the significance of the forward voltage difference between these parts?

A: The ABS4U exhibits 1.1 V forward voltage versus 1 V for the CBRLD1-04 TR13 at 1 A. This 0.1 V difference is typical among standard bridge rectifier variants and does not affect circuit functionality in standard rectification applications.

Q: Why is reverse leakage lower in the ABS4U?

A: The ABS4U demonstrates 5 µA reverse leakage at 400 V compared to 10 µA for the CBRLD1-04 TR13. This reflects manufacturing process improvements in the active ABS4U product line and indicates superior device characteristics.

Q: Are there packaging or tape & reel considerations?

A: The CBRLD1-04 TR13 is supplied in standard packaging. The ABS4U is available in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: Does the ROHS3 compliance of the ABS4U affect compatibility?

A: No. ROHS3 compliance indicates environmental and regulatory adherence and does not impact electrical or mechanical compatibility. This certification supports modern manufacturing and supply chain requirements.
